The MOTU HD192 high- definition 192-kHz audio interface is designed for those who demand the very best audio quality available. Equipped with the latest generation 24-bit, enhanced multi-bit 128x oversampling 192-kHz converters, the HD192 achieves a remarkable A-weighted signal-to-noise ratio of 120 dB with balanced XLR connectors throughout. Ideal for surround applications, the HD192's 12 inputs and 12 outputs can support two simultaneous 5.1 mixes. And the HD192 is full of advanced features, like AES/EBU I/O with sample rate conversion both in and out.

The PCI-424 card introduced with the 2408mk3 is 192-kHz ready. Just connect the HD192 expansion interface to record 192-kHz audio.

The HD192 can be purchased as an expander for an existing PCI-424-based MOTU Audio System, or as a core system which includes the PCI-424 card and Audiodesk workstation software.

The HD192's front panel provides dedicated 19-segment level meters for all 12 inputs and outputs. Two over meters are included, a temporary over meter and an over/hold meter that is resettable via software. Comprehensive clock status LEDs are also included so you can see at a glance the current sampling rate and clock source.

The HD192 features stereo AES/EBU digital I/O with built in sample rate conversion. This gives you the ability to integrate external digital audio sources, no matter what the sample rate, while recording audio at higher sample rates on the analog I/O of the HD192. For example, you can still take advantage of the 96-kHz digital I/O on your favorite outboard reverb, while recording audio at 192-kHz.

The HD192 audio interface provides industry standard word clock input and output. The word clock input allows the HD192 to synchronize smoothly with today's digital audio studio. The word clock output can be used as a master clock to drive other digital devices in your studio, such as a digital mixer. The AES digital I/O can be driven separately via a dedicated word clock input. You can even slave to a 48kHz clock source, even when the HD192 is operating at 192-kHz.
